Jiya swam 200 meters more than Molly. Jiya swam a total of 800 meters. How many meters did Molly swim?

Answer:

y=-5x+6

Step-by-step explanation:

To find your slope (or m value), you must identify 2 points that your line crosses through (I used (1,1) and (0,6). You can either count up and over to the point (0,6) from (1,1), or you can use the formula y2-y1/x2-x1 (it would look like 6-1/0-1). This will give you -5 for your slope.

Your x-intercept (or b value) is 6 because you can see from the graph that that is where your line intercepts y.

I hope this helped :)

If we pick a card, roll a die, and find the sum , the different sums possible is 17.

A permutation is an act of arranging the objects or numbers in order.

Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.

If we pick any card and roll a die

The sum possible is

The highest it can be would be  13(card) + 6(die)  =19

the Lowest it can be would be 1(card) + 1 (die)  = 2

So the different sums possible is 19-2 = 17.

Answer:

16.69°

Step-by-step explanation:

Given that,

Height of the building, h = 60 foot

Distance from the base of the building, b = 60 foot

We need to find the angle of elevation must the plane takes off in order to avoid crashing into the building. So,

[tex]\tan\theta=\dfrac{60}{200}\\\\\theta=\tan^{-1}\dfrac{60}{200}\\\\=16.69^{\circ}[/tex]

So, the required angle is 16.69°.

Answer:

Instead of adding the exponents of 2 to get four you should just leave the exponent as two in the final answer.

By utilizing trigonometric identities,we got cos 2θ = -1519/1681.

Given that sin θ = 40/41 and θ is a positive acute angle, we can find cos θ using the Pythagorean identity sin²θ + cos²θ = 1. Rearranging the equation, we have cos²θ = 1 - sin²θ.

Substituting the given value, we get cos²θ = 1 - (40/41)² = 1 - 1600/1681 = 81/1681.

Now, we can find cos 2θ using the double-angle identity cos 2θ = cos²θ - sin²θ.

Substituting the known values, we have

cos 2θ = (81/1681) - (40/41)² = 81/1681 - 1600/1681 = -1519/1681.

Therefore, cos 2θ = -1519/1681.

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationships ...

  Cos = Adjacent/Hypotenuse

  Tan = Opposite/Adjacent

Translated to the figure at hand, these are ...

  cos(35°) = 10/y   ⇒   y = 10/cos(35°) ≈ 12.21

  tan(35°) = x/10   ⇒   x = 10·tan(35°) ≈ 7.00

Step-by-step explanation:

The cost for each pound of trail mix is $1.5 and each pound of jelly beans is $3.5 .

The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.

According to the question

A store is having a sale on trail mix and jelly beans .

Let trail mix = T

and  jelly beans = J

For 5 pounds of trail mix and 3 pounds of jelly beans, the total cost is $18.

i.e

5T + 3J = 18 -------------------------- (1)

For 2 pounds of trail mix and 12 pounds of jelly beans, the total cost is $45.  

i.e

2T + 12J = 45 -------------------------------(2)

Now,

multiplying eq (1) from 4

20T + 12J = 72 -----------------(3)

Solving equation (3) and (2) the equation by elimination method

20T + 12J = 72 -----------------(3)

2T + 12J = 45  -------------------------(2)

subtracting equation (2) from (3)

18T = 27

T = 1.5

substituting the value of T in equation 1

5T + 3J = 18

5*1.5 + 3J = 18

7.5 + 3J = 18

3J = 18 - 7.5

3J = 10.5

J = 3.5

Hence, the cost for each pound of trail mix is $1.5 and each pound of jelly beans is $3.5 .

Michela needs to increase her speed by 0.23 miles/hour to attain her goal.

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

As per the given,

She runs 5 miles in 52 minutes.

5 miles in (52/60) hour

In 1 hour → 5(60/52) = 300/52 = 5.769

Her goal was 6 miles in 1 hour.

5.769 + x = 6

x = 0.23 miles/hour

Hence "Michela needs to increase her speed by 0.23 miles/hour to attain her goal".
